Here is a short demonstration video of the split mode as implemented in the original Linnstrument. By using the split mode one can access all 200 pads. With a judicious selection of synthesizer and range one can extend a tuning well beyond the current midi standard of 128 notes. The short demonstration piece uses two non-octave tunings => 5/4 divided into 4 and 5/4 divided into 8 notes respectively.

standing in the cornfield you watch the corn grow and
the searing hot days pass on to night to day to night to day,
taller and taller, until you are one with all there is…
for you are one of them…
your roots dig soil,
your stalk stretches greedily for every ray of the murdering sun
in the anguish of a midsummer’s thirst…
Aeolian Edit 2 is an experiment with manipulation of an electric aeolian harp sample which I added counterpoint and retuned to 17 edo (equal division of the octave). Since the electric aeolian harp yields only harmonics what has been manipulated are the pitch values that the melodyne detection routine decided were root pitches and *not* harmonics. By retuning to 17 I have recomposed the original content into something other than a pure harmonic relationship. My apologies for the large volume changes – in this case I’d rather have close to a constant loudness but do not have that worked out yet.
Simple Passwords is a proof of concept improvisation. Here I use Fractal Tune Smithy 3 to retune my Linnstrument’s output in real time to play Moog’s iPad app Animoog connected by rtpMIDI in a decidedly microtonal tuning via pitch bends. – Its not perfect as some shifts are heard in held notes,though as with my gr-20 retuning work I feel confident this will be worked out once I find the proper settings. Frankly I find this to be exciting because almost any iPad app can be played in an alternate tuning by this method.

I put a GK-3 hex pick up on my 19 edo guitar – what follows are three demonstration pieces that rely on the pitch interpretation of the GP-10 processor. My overall impression that this was successfully accomplished as you can clear hear places where I pushed a decidedly non-12 equal note(s) through the system.
Distorted harmony in C major (intended to be 12 edo harmony which gets “bent”)
fanfare for a helium shrouded exoplanet (unconstrained pitch and percussion) for two ebows and two spring reverb units. Reverb unit MOD P-RMOD-8AB2A1B ($26 – 3 short springs) and Gibbs Manufacturing and Research unit salvaged from a Sears silver tone organ ($0 – 4 spring joined to make 2 long springs) – two tracks with each spring reverberation unit played by two ebows. In the midst of all of the noise incredible resonances with and without beating occur.
Cameron Bobro did something I thought impossible – used this piece as a ground to improvise clarinet over!
In this presentation I use Jam Origin’s MIDI Guitar to send a microtonally retuned MIDI stream to Kontakt 5’s string ensemble. The guitar was run through the cakewalk amp sim. In the top graphic I show where the microtonal midi machine is loaded (lower right) and in the next graphic I show the interface of the microtonal machine. A key is to enable the same amount of pitch bend in MIDI guitar as well as the VSTi you are using. In this case it was the standard 2 whole tones. In the sound demo you can hear the 12 equal guitar playing single notes to full chords in 12 equal and at the same time the Kontakt strings in 125 cents per step tuning driven by the Jam Origin included audio VSTi. In sonar be sure to enable MIDI guitar’s midi out in order to put it into the list of your VSTi.
The midi file that I found is of medium quality and this is decidedly a demonstration piece – this tune was chosen because it is a favorite of Gene’s. To get around having to transpose each note individually or as a pitchclass I use the method of picking 12 notes out of the 27 note set and used that to retuned Garritan Concert and Marching Band samples. The actual tuning is listed below. I think it notable that the rather large deviations from 12 equal, where each step is exactly 100 cents, is not very evident if at all.

The Coming Storm is a 25 minute recording of a thunderstorm that approaches and then releases a deluge of rain. The sounds are a combination of wind blown harmonics, the clicks of lightning, and then play of the strings of the harp by the rain as well as wind. There is some residual background noise that I can’t remove without removing the lightning strikes so it was left in. A surprising (to me) variety of sounds result from this onslaught of nature. Metallic clinks, almost light saber-esque stabs, and the sound of huge things being dragged violently across the harp. Starts out quiet and gets pretty loud.
This is a 24 minute long piece, it will take a while to load and play.
What Have I Done is an ambient setting of a poem I wrote which was recited by Bethan Mathis. We are slowly working on an album together. The music are selected recordings of my Electric Aeolian Harp. Additionally there are field recordings that I made and from Freesound.org field recordings by martian, digifishmusic and looijenga.
